More than 30 states have laws that allow people to use deadly force if they have a reasonable fear for their life or property. But this week, a Montana jury said that type of law has its limits, finding a homeowner who shot a teenager in his garage guilty of deliberate homicide.

In the early hours of April 27, a motion detector alerted homeowner Markus Kaarma someone was in the garage of his home in Missoula, Mont. He went outside and almost immediately fired four shotgun blasts, killing 17-year-old Diren Dede, a German exchange student.

Closing arguments finished today in the murder trial of a Missoula man who shot and killed a German exchange student last April.

Markus Kaarma fired a shotgun four times into his garage, killing 17-year-old Diren Dede.

Kaarma’s defense team said he was simply a scared homeowner defending his family against burglars who had already victimized Kaarma twice. Lead defense attorney Paul Ryan said Montana’s Castle Doctrine gives Kaarma special protection.

Opening arguments began in the Markus Kaarma case today in Missoula. Kaarma’s accused of murdering 17-year-old German exchange student, Diren Dede after the boy entered his garage late on the night of April 27.

The state’s 15-minute opening argument started with Assistant City Attorney Jennifer Clark reenacting a plea from Dede.

“NO NO NO NO PLEASE, that’s what Janelle said Darren was pleading right before he was shot, on April 27th, 2014."

Missoula County District Court Judge Ed McLean today laid it out in no uncertain terms to Markus Kaarma's lead attorney, Paul Ryan:

"I don't want any playing to the public. We have serious business at hand and it's not the time to run a public relations campaign, so knock it off."

McLean was referring to the announcement that tomorrow morning, in Missoula's Caras Park, Ryan's law firm would host a live screening of the World Cup soccer match between the United States and Germany.
